BELT LACER.

Application filed March so, 1925. Serial a... 19.479.

To all whom it may concern:

Be it known that I, JAMES K. DIAMOND, a citizen of the United States, residing at Grand Rapids, county of Kent, State of Michigan, have invented certain new and useful Improvements in Belt Lacers, of which the following is a specification.

This invention relates to improvements in belt lacers.

.The main object of this invention is to provide an improved belt lacing hook which may be set into the belt in a very uniform manner.

Objects pertaining to details and economies of my improvements will definitel appear fromthe detailed description to fo low..

I accomplish the objects of my invention by the devices andmeans described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing forming a part of this application, in which:

Fig. I is a sideview of one of my 1mproved belt lacing hooks open.

Fig. II is a detail longitudinal section of a belt lacing embodying my improved lacing hook.

Fig. III is a fragmentary transverse section on a line corresponding to line 3-3 of Fig. II, the hooks being shown in full lines for convenience in illustration. Fig. IV is a fragmentary section on a line corresponding to line 44 of Fig. II.

Fig. V is a detail view illustrating the setting of the hook and some of the advantages of the hook in setting.

In the drawing similar numerals of refer- .ence refer to similar parts in all of the views, and the sectional views are taken looking in the direction of the little arrows.

to the paralleliportions. The diverging portions of the; arms 3 are preferably of the same length as in the embodiment illustrated. I

Inpractice a plurality of these hooks are simultaneouslyset into the belt, setting tools ofdifferent types adapted to close or force the hooksinto the belt being provided.

In Fig. I illustrate a device for setting or applying the hooks which comprises a holder 6 having slots 7 adapted to receive the. hooks, the hooks being retained within the slots by the pin 8. The jaws. 9 are carried by the pivoted arms 10, the jaws being mounted upon .the arms for limited tilting movement. ,This device, with a plurality ofhooks therein, is placed within a vise, the jaws of which are indicated at 11. The closing of the vise forces the jaws 9 together, forcing the prongs into the. belt and straightening the arms of the hook as shown in Fig. II.

. minimized. The prongs 5 are flattened at 5 preferably on opposed sides as illustrated, thereby providing clinching points which are adapted to turn laterally to the longitudinal planev of. the hook when the hooks are set, the direction of their clinching being thus predetermined, that is, they are clinched in a lateral direction thus gripping the fibre of the belt at the side of the prong and a portion of the belt which is not broken or cut by the entrance of the prong, as is clearly shown in Figs. III and IV. Where the arms of the hook diverge from the bight thereof to the prongs as shown inthe Conn Patent No. 77 9,587 there is a tendency for certain of the prongs to be distorted as by striking a portion of the belt more dense than other portions. By providing'these parallel portions 4 with the prongs dlsposed at right angles thereto this tendency is minimized. Further, the parallel portions engaging the jaws of the setting device, the tendency of the closing action of the jaws to tilt the prongs is also minimized.

Having thus described my invention, what I claim as new and desire to secure'by Letters Patent, is:

1. As an article of manufacture, a belt BELT I fit) lacing hook having outwardly diverging arms of unequal length, the arms having parallel portions at their outer ends terminating in. inwardly directed prongs disposed at right angles to the parallel portions, the adjacent sides of the prongs being flattened t taper the prongs and provide clinching points adapted when set to turn laterally relative to the longitudinal plane of the hook.

2; As an article of inanufacture a belt lacing hook having outwardly diverging arrris of unequal lengthg the arms having parallel portions at their outer ends, the diverging portions being of the same length said parallel portions terminating in inwardly directed prongs disposed atright angles to the parallel portions and conforined to provide clinching points. adapted to turn laterally relative to the longitudinal plane of the hooks. 1
